Customers are saying

Customers frequently mention the 750VA Battery Back-Up System's great size, reliable battery life, and overall performance. Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    This is pretty good for the cost. The battery itself isn't the longest lasting if you're have a lot of high draw equipment running on it; but it does give a decent enough buffer to safely turn everything off in the event of a power outage.

    This works great, it keeps my modem and router running during power outages for hours though. It does beep whenever the power is out though. It could be i just don't know how to disable it, but its really not a big deal.

    It has enough sockets, along with two USB connections, and give me about 7 minutes of power in case of an outage. That's more than I need.

    We keep having voltage flickers that lasted just long enough to shut our computer down requiring a restart. This solved the problem.

    Very nice unit as it fits perfectly on my shelf to be a backup for my router. Has wall mounting capability which could be nice for some. Key thing is with the size may be tough to plug in many of those large power block size plugs.

    Have had this for a couple of months, haven't lost power yet but have heard a few clicks during storms indicating a hit to the current I guess, with no impact to my equipment. I like the vertical form factor, takes up alot less room. Have PC, monitor, modem/router and external drives connected and still have some slots open. I had previous issue with APC unit so decided to go with Cyberpower. So far so good.

    Bit of advice : after several power surges, these will degrade over time according to Geek squad , when my BRAND NEW computer was hooked up to an older battery backup like this , it didn’t protect my computer. Hence I am buying another one ... if it’s not one thing it’s another...
